 the pen cap is provided with a limiting structure and a second elastic component; 
 the limiting structure is configured to control a state of the one or more protrusions; and 
 when the limiting structure is in a non-limiting state, in response to the one or more protrusions being subjected to an action of pressure, the one or more protrusions move along an axial direction of the one or more protrusions under the action of the pressure and such that the second elastic component undergoes an elastic deformation. 
 
     
     
       2. The marker pen of  claim 1 , wherein a ratio between a height of the first protrusion and a depth of the groove is 0.5:1 to 1:1.

       4. The marker pen of  claim 1 , wherein the pen cap includes a top surface and four side surfaces;
 the top surface is provided with a first protrusion and a second protrusion; 
 each of the four side surfaces is provided with a plurality of first protrusions and a plurality of second protrusions; and 
 a count of protrusions is equal on the each of the four side surfaces, and a count of the first protrusions is equal to a count of the second protrusions. 
 
     
     
       5. The marker pen of  claim 4 , wherein the first protrusion and the second protrusion disposed on the top surface are provided along a first symmetry axis of the top surface and are symmetrically distributed relative to a second symmetry axis, and the first symmetry axis is perpendicular to the second symmetry axis. 
     
     
       6. The marker pen of  claim 4 , wherein for different side surfaces of the four side surfaces, arrangements of the plurality of protrusions are different; and
 for each side surface of the four side surfaces, there exists an arrangement on another identical pen cap that mates with the pen cap. 
 
     
     
       7. The marker pen of  claim 6 , wherein the plurality of protrusions are arranged in a dotted pattern, and a distance between center points of two adjacent protrusions in a vertical direction or a horizontal direction is 4.8 mm to 7.2 mm. 
     
     
       8. The marker pen of  claim 4 , wherein an edge of the top surface has a cylindrical protrusion. 
     
     
       9. The marker pen of  claim 8 , wherein an outer side surface of the cylindrical protrusion and an edge shape of the top surface are different. 
     
     
       10. The marker pen of  claim 1 , wherein the pen cap is provided with a turntable, and the one or more protrusions are provided on the turntable. 
     
     
       11. The marker pen of  claim 1 , wherein the one or more protrusions include at least three protrusions, the at least three protrusions have at least three extension directions, and the at least three extension directions include an x-axis direction, a y-axis direction, and a non-coordinate axial direction; and
 the x-axis direction refers to a direction that is perpendicular to an axial direction of the marker pen, the y-axis direction refers to a direction that is parallel to the axial direction of the marker pen, and the non-coordinate axis direction is not perpendicular to either the x-axis direction or the y-axis direction. 
 
     
     
       12. The marker pen of  claim 11 , wherein at least one protrusion extending along the y-axis direction mates with at least one protrusion extending along the non-coordinate axial direction. 
     
     
       13. The marker pen of  claim 11 , wherein at least one protrusion extending along the x-axis direction includes the first protrusion and the second protrusion, and the first protrusion and the second protrusion are disposed opposite to each other. 
     
     
       14. The marker pen of  claim 1 , wherein a first elastic component is provided within the body configured to adjust a length of the body. 
     
     
       15. The marker pen of  claim 1 , wherein the one or more protrusions includes a first extension section, a second extension section, and a turning structure, the first extension section and the second extension section are rotatably connected by the turning structure, and extending directions of the first extension section and the second extension section are different.
